The perfect choice for a short jaunt up the Topagna Canyon trail or during your morning workout, the 18 oz. Standard Mouth's flex cap functions as a "suction cup" and is thus 100% leak-proof. The flex cap is also equipped with a durable carrying piece so that you can easily carry it on two fingers during your hike. But most important in a water bottle is its ability to keep your water cold. With its double-walled stainless steel insulation, the 18 oz. Standard Mouth will keep your water cold for up to 24 hours and hot for up to 12 hours in those cases in which you prefer tea over water. Like all Hydro Flask products, the 18 oz. Standard Mouth is made from non-toxic BPA-free plastics & 18/8 stainless steel and features a coated slip-free exterior for maximum grip, meaning it wont slip out of your backpack's side water bottle pocket and won't develop condensation. We recommend washing by hand with mild dish soap instead of running it through the dishwasher.
